Problem:
The environment is Tomcat 5.5.20 + Hibernate EM 3.3 + Seam 1.2.0 + Microcontainer. I'm trying to build a simple clickable list with editing, everything works fine (querying, updating), except when adding a new record:
UserBean.java
@Name ("userBean")
@Scope (ScopeType.CONVERSATION)
public class UserBean extends EntityController implements Serializable {
@DataModelSelection
@Out (required = false)
private User selectedUser;
@DataModel
private List<User> users;
public void addUser() {
selectedUser = new User();
}
public void cancelEdit() {
selectedUser = null;
}
@Factory ("users")
@Begin (flushMode = FlushModeType.MANUAL)
public void createRecords() {
users = createQuery("SELECT u FROM User u").getResultList();
}
@Transactional (TransactionPropagationType.REQUIRED)
public void saveUser() {
persist(selectedUser);
flush();
addFacesMessage("User #{selectedUser.username} succesfully saved");
createRecords();
}
public void selectUser() {
}
}
users.xhtml (I'm using Facelets):
